Cognitive password entry system

ABSTRACT

An aspect includes a cognitive password entry system. A processor detects a login attempt targeting a website for a user identifier having a previously stored instance of a password associated with the user identifier. A number of login attempts is monitored since the password was manually entered at the website. The processor determines whether a prompting period has been reached based on the number of login attempts meeting a prompting period threshold. The stored instance of the password is used as an entered password for the login attempt based on determining that the prompting period has not been reached. A cognitive aid prompt is output based on determining that the prompting period has been reached.

BACKGROUND

The present invention relates to computer systems, and morespecifically, to a cognitive password entry system.

In existing password entry systems, there is only a binary choice ofallowing passwords to be saved or not allowing passwords to be saved.Once a password is saved, password entry systems typically auto-fill thepassword upon encountering a login attempt at a website associated withthe saved password. Passwords are typically stored locally to a device;however, if the user attempts to access the same website from adifferent device that does not have access to the stored password, theuser must recall the password and manually enter it. If the user has notrecently or frequently entered the password, the user may have forgottenthe password and be forced to reset the password for accessing thewebsite, which can also lead to problems on other devices where theprevious version of the password is still stored.

SUMMARY

According to embodiments of the present invention, a method, system, andcomputer program product are provided for cognitive password entry. Aprocessor detects a login attempt targeting a website for a useridentifier having a previously stored instance of a password associatedwith the user identifier. A number of login attempts is monitored sincethe password was manually entered at the website. The processordetermines whether a prompting period has been reached based on thenumber of login attempts meeting a prompting period threshold. Thestored instance of the password is used as an entered password for thelogin attempt based on determining that the prompting period has notbeen reached. A cognitive aid prompt is output based on determining thatthe prompting period has been reached.

DETAILED DESCRIPTION

Embodiments described herein are directed to a password entry systemthat facilitates password use and memorization in an environment inwhich systems (e.g., systems accessed with Web pages) may “remember” apassword on one device but not on another device, thus sometimes causingusers to forget passwords when attempting access from various personaldevices. Embodiments provide a cognitive aid so that a user need not gothrough a password recovery process when using multiple devices or inother scenarios. A password-entry system can store a password andpresent cognitive aid prompts at a designated rate (e.g., rate R) forthe password, even if the password is remembered by the user. As oneexample, a user may be required to enter the password every third time(even though the system has been asked to store the password) so as toassist in recall of the password by the user over an extended period oftime.

Embodiments provide an option to save a password but generate a promptto reenter the password at a particular rate so that, for example, onthe fifth time accessing the website there will be a request to manuallyenter the password even though an instance of the password has beenstored for accessing the website. The prompt (referred to as a cognitiveaid prompt) serves as a reminder and may make it easier for the user toremember the password while still saving it for faster entry into thewebsite.

Another example of cognitive aid prompts that encourage recall throughrepeated exposure to associative cues for a given password may involvethe use of correlated contexts. Currently, as a security feature, manywebsites present a picture, chosen by the user, at the password entryscreen. This picture is often derived from a server other than the oneserving up the password entry component, and makes it more difficult fora malicious entity to spoof the password entry screen without failing todisplay (or displaying incorrect) associated images. In combination withor in addition to a security-based image, a cognitive aid image can beprovided to assist in establishing a context by which a user mayremember the password itself. The cognitive aid image can be sourcedfrom a different server than the security-based image.

Embodiments can include automatically generated associative context inmany forms, such as a three-dimensional virtual room or environment inwhich the password has been entered previously. Visual depictions ascognitive aids can be arbitrary, as there is no direct link to systemsecurity. Another example of an associative context form includes theuse of a mnemonic to assist the user in remembering the password, e.g.,a simulated kinesthetic mnemonic for the password.

It is understood in advance that although this disclosure includes adetailed description on cloud computing, implementation of the teachingsrecited herein are not limited to a cloud computing environment. Rather,embodiments of the present invention are capable of being implemented inconjunction with any other type of computing environment now known orlater developed.

Cloud computing is a model of service delivery for enabling convenient,on-demand network access to a shared pool of configurable computingresources (e.g. networks, network bandwidth, servers, processing,memory, storage, applications, virtual machines, and services) that canbe rapidly provisioned and released with minimal management effort orinteraction with a provider of the service. This cloud model may includeat least five characteristics, at least three service models, and atleast four deployment models.

Characteristics are as follows:

On-demand self-service: a cloud consumer can unilaterally provisioncomputing capabilities, such as server time and network storage, asneeded automatically without requiring human interaction with theservice's provider.

Broad network access: capabilities are available over a network andaccessed through standard mechanisms that promote use by heterogeneousthin or thick client platforms (e.g., mobile phones, laptops, and PDAs).

Resource pooling: the provider's computing resources are pooled to servemultiple consumers using a multi-tenant model, with different physicaland virtual resources dynamically assigned and reassigned according todemand. There is a sense of location independence in that the consumergenerally has no control or knowledge over the exact location of theprovided resources but may be able to specify location at a higher levelof abstraction (e.g., country, state, or datacenter).

Rapid elasticity: capabilities can be rapidly and elasticallyprovisioned, in some cases automatically, to quickly scale out andrapidly released to quickly scale in. To the consumer, the capabilitiesavailable for provisioning often appear to be unlimited and can bepurchased in any quantity at any time.

Measured service: cloud systems automatically control and optimizeresource use by leveraging a metering capability at some level ofabstraction appropriate to the type of service (e.g., storage,processing, bandwidth, and active user accounts). Resource usage can bemonitored, controlled, and reported providing transparency for both theprovider and consumer of the utilized service.

Service Models are as follows:

Software as a Service (SaaS): the capability provided to the consumer isto use the provider's applications running on a cloud infrastructure.The applications are accessible from various client devices through athin client interface such as a web browser (e.g., web-based e-mail).The consumer does not manage or control the underlying cloudinfrastructure including network, servers, operating systems, storage,or even individual application capabilities, with the possible exceptionof limited user-specific application configuration settings.

Platform as a Service (PaaS): the capability provided to the consumer isto deploy onto the cloud infrastructure consumer-created or acquiredapplications created using programming languages and tools supported bythe provider. The consumer does not manage or control the underlyingcloud infrastructure including networks, servers, operating systems, orstorage, but has control over the deployed applications and possiblyapplication hosting environment configurations.

Infrastructure as a Service (IaaS): the capability provided to theconsumer is to provision processing, storage, networks, and otherfundamental computing resources where the consumer is able to deploy andrun arbitrary software, which can include operating systems andapplications. The consumer does not manage or control the underlyingcloud infrastructure but has control over operating systems, storage,deployed applications, and possibly limited control of select networkingcomponents (e.g., host firewalls).

Deployment Models are as follows:

Private cloud: the cloud infrastructure is operated solely for anorganization. It may be managed by the organization or a third party andmay exist on-premises or off-premises.

Community cloud: the cloud infrastructure is shared by severalorganizations and supports a specific community that has shared concerns(e.g., mission, security requirements, policy, and complianceconsiderations). It may be managed by the organizations or a third partyand may exist on-premises or off-premises.

Public cloud: the cloud infrastructure is made available to the generalpublic or a large industry group and is owned by an organization sellingcloud services.

Hybrid cloud: the cloud infrastructure is a composition of two or moreclouds (private, community, or public) that remain unique entities butare bound together by standardized or proprietary technology thatenables data and application portability (e.g., cloud bursting forload-balancing between clouds).

A cloud computing environment is service oriented with a focus onstatelessness, low coupling, modularity, and semantic interoperability.At the heart of cloud computing is an infrastructure comprising anetwork of interconnected nodes.

Referring now to FIG. 1, illustrative cloud computing environment 50 isdepicted. As shown, cloud computing environment 50 comprises one or morecloud computing nodes 10 with which local computing devices used bycloud consumers, such as, for example, personal digital assistant (PDA)or cellular telephone 54A, desktop computer 54B, laptop computer 54C,and/or automobile computer system 54N may communicate. Nodes 10 maycommunicate with one another. They may be grouped (not shown) physicallyor virtually, in one or more networks, such as Private, Community,Public, or Hybrid clouds as described hereinabove, or a combinationthereof. This allows cloud computing environment 50 to offerinfrastructure, platforms and/or software as services for which a cloudconsumer does not need to maintain resources on a local computingdevice. It is understood that the types of computing devices 54A-N shownin FIG. 1 are intended to be illustrative only and that computing nodes10 and cloud computing environment 50 can communicate with any type ofcomputerized device over any type of network and/or network addressableconnection (e.g., using a web browser).

Referring now to FIG. 2, a set of functional abstraction layers providedby cloud computing environment 50 (FIG. 1) is shown. It should beunderstood in advance that the components, layers, and functions shownin FIG. 2 are intended to be illustrative only and embodiments of theinvention are not limited thereto. As depicted, the following layers andcorresponding functions are provided:

Hardware and software layer 60 includes hardware and softwarecomponents. Examples of hardware components include: mainframes 61; RISC(Reduced Instruction Set Computer) architecture based servers 62;servers 63; blade servers 64; storage devices 65; and networks andnetworking components 66. In some embodiments, software componentsinclude network application server software 67 and database software 68.

Virtualization layer 70 provides an abstraction layer from which thefollowing examples of virtual entities may be provided: virtual servers71; virtual storage 72; virtual networks 73, including virtual privatenetworks; virtual applications and operating systems 74; and virtualclients 75.

In one example, management layer 80 may provide the functions describedbelow. Resource provisioning 81 provides dynamic procurement ofcomputing resources and other resources that are utilized to performtasks within the cloud computing environment. Metering and Pricing 82provide cost tracking as resources are utilized within the cloudcomputing environment, and billing or invoicing for consumption of theseresources. In one example, these resources may comprise applicationsoftware licenses. Security provides identity verification for cloudconsumers and tasks, as well as protection for data and other resources.User portal 83 provides access to the cloud computing environment forconsumers and system administrators. Service level management 84provides cloud computing resource allocation and management such thatrequired service levels are met. Service Level Agreement (SLA) planningand fulfillment 85 provides pre-arrangement for, and procurement of,cloud computing resources for which a future requirement is anticipatedin accordance with an SLA.

Examples of workloads andfunctions which may be provided from this layer include: mapping andnavigation 91; software development and lifecycle management 92; virtualclassroom education delivery 93; data analytics processing 94;transaction processing 95; and various workloads 96. Although FIG. 2depicts workloads layer 90 above management layer 80, workloads need notsend I/O requests through management layer 80 to reach virtualizationlayer 70. In some embodiments, management layer 80 and workloads layer90 can both directly interact with virtualization layer 70, andworkloads of workloads layer 90 can operate in conjunction with orindependent of management layer 80.

Referring now to FIG. 3, a schematic of an example of the cloudcomputing node 10 of FIG. 1 is shown. Cloud computing node 10 is onlyone example of a suitable cloud computing node and is not intended tosuggest any limitation as to the scope of use or functionality ofembodiments of the invention described herein. Regardless, cloudcomputing node 10 is capable of being implemented and/or performing anyof the functionality set forth hereinabove.

In cloud computing node 10 there is a computer system/server 12, whichis operational with numerous other general purpose or special purposecomputing system environments or configurations. Examples of well-knowncomputing systems, environments, and/or configurations that may besuitable for use with computer system/server 12 include, but are notlimited to, personal computer systems, server computer systems, thinclients, thick clients, hand-held or laptop devices, multiprocessorsystems, microprocessor-based systems, set top boxes, programmableconsumer electronics, network PCs, minicomputer systems, mainframecomputer systems, and distributed cloud computing environments thatinclude any of the above systems or devices, and the like.

Computer system/server 12 may be described in the general context ofcomputer system executable instructions, such as program modules, beingexecuted by a computer system. Generally, program modules may includeroutines, programs, objects, components, logic, data structures, and soon that perform particular tasks or implement particular abstract datatypes. Computer system/server 12 may be practiced in distributed cloudcomputing environments where tasks are performed by remote processingdevices that are linked through a communications network. In adistributed cloud computing environment, program modules may be locatedin both local and remote computer system storage media including memorystorage devices.

As shown in FIG. 3, computer system/server 12 in cloud computing node 10is shown in the form of a computing device. The components of computersystem/server 12 may include, but are not limited to, one or moreprocessors or processing units 16, a system memory 28, and a bus 18 thatcouples various system components including system memory 28 toprocessor 16.

Bus 18 represents one or more of any of several types of bus structures,including a memory bus or memory controller, a peripheral bus, anaccelerated graphics port, and a processor or local bus using any of avariety of bus architectures. By way of example, and not limitation,such architectures include Industry Standard Architecture (ISA) bus,Micro Channel Architecture (MCA) bus, Enhanced ISA (EISA) bus, VideoElectronics Standards Association (VESA) local bus, and PeripheralComponent Interconnects (PCI) bus.

Computer system/server 12 typically includes a variety of computersystem readable media. Such media may be any available media that isaccessible by computer system/server 12, and it includes both volatileand non-volatile media, removable and non-removable media.

System memory 28 can include computer system readable media in the formof volatile memory, such as random access memory (RAM) 30 and/or cachememory 32. Computer system/server 12 may further include otherremovable/non-removable, volatile/non-volatile computer system storagemedia. By way of example only, storage system 34 can be provided forreading from and writing to a non-removable, non-volatile magnetic media(not shown and typically called a “hard drive”). Although not shown, amagnetic disk drive for reading from and writing to a removable,non-volatile magnetic disk (e.g., a “floppy disk”), and an optical diskdrive for reading from or writing to a removable, non-volatile opticaldisk such as a CD-ROM, DVD-ROM or other optical media can be provided.In such instances, each can be connected to bus 18 by one or more datamedia interfaces. As will be further depicted and described below,memory 28 may include at least one program product having a set (e.g.,at least one) of program modules that are configured to carry out thefunctions of embodiments of the invention.

Program/utility 40, having a set (at least one) of program modules 42,may be stored in memory 28 by way of example, and not limitation, aswell as an operating system, one or more application programs, otherprogram modules, and program data. Each of the operating system, one ormore application programs, other program modules, and program data orsome combination thereof, may include an implementation of a networkingenvironment. Program modules 42 generally carry out the functions and/ormethodologies of embodiments of the invention as described herein.

Computer system/server 12 may also communicate with one or more externaldevices 14 such as a keyboard, a pointing device, a display 24, etc.;one or more devices that enable a user to interact with computersystem/server 12; and/or any devices (e.g., network card, modem, etc.)that enable computer system/server 12 to communicate with one or moreother computing devices. Such communication can occur via Input/Output(I/O) interfaces 22. Still yet, computer system/server 12 cancommunicate with one or more networks such as a local area network(LAN), a general wide area network (WAN), and/or a public network (e.g.,the Internet) via network adapter 20. As depicted, network adapter 20communicates with the other components of computer system/server 12 viabus 18. It should be understood that although not shown, other hardwareand/or software components could be used in conjunction with computersystem/server 12. Examples, include, but are not limited to: microcode,device drivers, redundant processing units, external disk drive arrays,RAID systems, tape drives, and data archival storage systems, etc.

Referring now to FIG. 4, a block diagram of a system 100 for cognitivepassword entry is depicted. A web browser 102 can execute on a computingdevice, such as one or the cloud computing nodes 10 of FIG. 1 and/or oneof the computing devices 54A-54N of FIG. 1. The web browser 102 cancommunicate with a website 104, e.g., within cloud computing environment50 of FIG. 1 or across another type of network connection, to reachlimited access content 106 that requires a password to access. Inembodiments a cognitive password service 108 is interposed in a passwordentry process between the web browser 102 and the website 104. Thecognitive password service 108 can be implemented in the cloud computingenvironment 50 of FIG. 1, for instance, as part of the management layer80 of FIG. 2 or may be implemented locally on a same computing device asthe web browser 102 and/or website 104 or elsewhere within a networkedenvironment.

The web browser 102 may retain stored passwords 110 in cookies 112associated with a particular user identifier and multiple websites,including website 104. The cognitive password service 108 can detect alogin attempt targeting website 104 for a user identifier having apreviously stored instance of a password associated with the useridentifier in the stored passwords 112. The cognitive password service108 need not track the actual passwords but may temporarily deactivateone of the cookies 110 associated with the user identifier and thewebsite 102 to prevent an associated password instance in the storedpasswords 112 from propagating to the website 104 until/unless thecognitive password service 108 determines that a prompting period hasnot been reached. For instance, the cognitive password service 108 canmonitor a number of login attempts since the password was manuallyentered at the website 104 and determine whether a prompting period hasbeen reached based on the number of login attempts meeting a promptingperiod threshold. Multiple prompting period thresholds 114 can betracked on a user identifier and website identifier basis. A promptingpolicy 116 can dynamically adjust the prompting period thresholds 114with a user-specific rate of decay based on one or more of: an elapsedtime since a last successful login, a level of password complexity, anda device type used to access the website 104.

A stored instance of a password can be passed from the stored passwords112 to the website 104 via the cognitive password service 108 as anentered password for a login attempt based on determining that theprompting period has not been reached. The cognitive password service108 can output a cognitive aid prompt selected from one or morecognitive aid prompts 118 based on determining that the prompting periodhas been reached.

In one embodiment, the cognitive password service 108 learns how oftento provide a cognitive aid prompt to a user based on an assessment ofthe user. For example, user1 needs to enter the password every threetimes, even though user1 has requested that the web browser 102 storethe password, but user2 must enter a password for the website 104 everyfive login times. The cognitive password service 108 may automaticallydetermine that a user is having a problem recalling a password, andchange the rate defined in the prompting period thresholds 114 for thespecific user. Additionally, the cognitive password service 108 mayadjust the prompting period thresholds 114 to establish a higher orlower frequency of outputting cognitive aid prompts 118 to the userbased on how often the user attempts to access the website 104.

In an embodiment, the user may request that the cognitive passwordservice 108 defer making a manual entry of the password for another timebecause the user is in a rush (and the password is already stored andavailable in the stored passwords 112). In an embodiment, the cognitivepassword service 108 may allow the stored instance of the password to bepassed to the website 104 upon detecting a partly mistyped the passwordin response to a cognitive aid prompt. Since the password has been savedin the stored passwords, rather than not granting access to the website104, the cognitive password service 108 may respond with a warningmessage, such as “the password you entered doesn't match your savedpassword.” Also, when mistyped, and because the system 100 is alreadyconfigured to allow a user to skip password entry altogether using thestored passwords 112, the cognitive password service 108 may coach theuser on how best to remember the password. For example, the sequence mayprogress as follows:

1. “The password you entered does not match your saved password. Pleasetry again.”

2. “You seem to be trying similar passwords.”

3. “You are getting warmer.”

4. “Good. You remembered! In the future, I advise you to think aboutthis website as the kind that accepts the second version of the passwordyou entered.”

5. “Would you like to create a cognitive associative context to bedisplayed whenever I ask you if you remember you password?”

6. “Please don't make the cognitive associative context an obviousdepiction of your password.”

7. “May I suggest the following cognitive associative context?”

In embodiments, rather than maintaining the stored passwords 112 locallyon the same computing device as web browser 102, the stored passwords112 can be stored elsewhere within the cloud computing environment 50 ofFIG. 1. For example, there can be a passwords cloud, and the cognitivepassword service 108 can maintain a table mapping user identifiers andwebsite identifiers to entries in the passwords cloud to store, update,and retrieve the stored passwords 112.

In embodiments, the prompting policy 116 can support user configurationof the prompting period thresholds 114 such that a user can establish adesired rate of cognitive aid prompting, for instance, using a graphicaluser interface such as a pulldown interface.

The prompting policy 116 may include selection controls that determinewhen and in what situation the cognitive aid prompts 118 are to beoutput. As an example, cognitive aid prompting may be enabled ordisabled depending on a history of past use, a department profile in acompany, a company profile, a reputation profile, a security profile, asocial network, a location of use, a device being used, a class ofdevice being used, the nature of website 104 being accessed, the natureof application being accessed for the limited access content 106, andthe like. The prompting policy 116 can adjust the prompting periodthresholds 114 based on factors such as a history of past use, adepartment profile in a company, a company profile, a reputationprofile, a security profile, a social network, a location of use, adevice being used, a class of device being used, the nature of website104 being accessed, the nature of application being accessed for thelimited access content 106, and the like.

FIG. 5 depicts an example of a cognitive aid prompt 200 according to anembodiment. The example of FIG. 5 illustrates a form of associativelearning that presents an associative context 202 as one or more images.The images of the associative context 202 may be user selectable orarbitrarily selected from the cognitive aid prompts 118 of FIG. 4. In anembodiment, the cognitive aid prompt 200 is output to a user interfaceat a predefined interval according to the prompting period thresholds114 of FIG. 4. In the example of FIG. 5, rather than asking the user tomanually re-enter the password associated with the used identifier forwebsite 104 of FIG. 4, the cognitive aid prompt 200 includes question204, “Do you remember your password?” The cognitive aid prompt 200provides user options 206 (i.e., YES/NO). Based on detecting a userselection of “YES”, the cognitive password service 108 of FIG. 4 canproceed with automatic password entry from the stored passwords 112 ofFIG. 4 to access to the website 104 of FIG. 4. Based on detecting a userselection of “NO”, the cognitive password service 108 of FIG. 4 mayinitiate an interactive password coaching session including a sequenceof two or more password coaching tips. If the user fails to recall thepassword upon coaching, the password can be reset.

Referring to FIG. 6, a process flow 300 for cognitive password entry isgenerally shown in accordance with an embodiment. In an embodiment, theprocessing shown in FIG. 6 is performed by the cognitive passwordservice 108 of FIG. 4 executing on one or more processors, such asprocessor 16 of FIG. 3. The process flow 300 is further described withrespect to FIGS. 1-5. When there are no saved passwords in the storedpasswords 112 associated with website 104, the user can login to thewebsite 104 and manually enter a password. The user may be presentedwith an option to save the password. Upon agreeing to save the passwordin the stored passwords 112, the cognitive password service 108 cancreate a record of the website 104 associated with a user identifier(which may be a machine identifier), a record that the password has beenstored (or a copy of the password), a prompting period threshold, andother data as may be needed to support the prompting policy 116. Userpreferences for the prompting policy 116 can be set globally for theuser or on a per website basis.

At block 302, a login attempt is detected by processor 16 executing thecognitive password service 108, where the login attempt targets website104 for a user identifier having a previously stored instance of apassword associated with the user identifier in the stored passwords112. At block 304, the processor 16 can monitor a number of loginattempts since the password was manually entered at the website 104.

At block 306, the processor 16 can determine whether a prompting periodhas been reached based on the number of login attempts meeting aprompting period threshold from the prompting period thresholds 114. Atblock 308, the stored instance of the password is used as an enteredpassword for the login attempt based on determining that the promptingperiod has not been reached. For instance, the cognitive passwordservice 108 can directly send or enable the web browser 102 to send astored password to auto-complete a password field on the website 104.The cognitive password service 108 can increment a prompting counterwith each access.

At block 310, a cognitive aid prompt from cognitive aid prompts 118 isoutput based on determining that the prompting period has been reached.Outputting can include sending the cognitive aid prompt from thecognitive password service 108 to the web browser 102 for display. Theoutputting of the cognitive aid prompt can be user enabled. Thecognitive aid prompt can be a request to manually enter the password.Alternatively, the cognitive aid prompt can be an associative context.The stored instance of the password can be used as the entered passwordfor the login attempt based on receiving an indication that the userremembers the password in response to the cognitive aid prompt or basedon detecting a partial match between the stored instance of the passwordand a manual entry received in response to the cognitive aid prompt.

An interactive password coaching session that includes a sequence of twoor more password coaching tips can be initiated based on determiningthat the stored instance of the password and a manual entry received inresponse to the cognitive aid prompt do not match. Alternatively, theuser can be presented with an error message but allowed access to thewebsite 104 using the stored instance of the password.

The prompting period may be user configurable by allowing specificuser-defined values to be set in the prompting period thresholds 114.The prompting period threshold can be dynamically adjusted according tothe prompting policy 116 based on one or more of: an elapsed time sincea last successful login, a likelihood of logging into the website 104from multiple computers, a level of password complexity, and a devicetype used to access the website. The prompting policy 116 can establishand adjust a user-specific rate of decay of the prompting periodthreshold. The likelihood of logging into the website 104 from multiplecomputers can be determined based on a designation of the website 104(e.g., a “mobile” site designation), a history of multiple devicesassociated with the user, a history of other users accessing the website104 from multiple devices, and/or other factors. The level of passwordcomplexity can include the number of password formation rules met by thepassword, such as a capital letter, a symbol, a letter, a number, etc. Ahigher degree of password complexity can result in lowering theprompting threshold, as the user will likely benefit from more frequentreminders. The device type may be used to enable/disable outputting ofthe cognitive aid prompts 118. For instance, when access occurs througha mobile phone, output of the cognitive aid prompts 118 can be blocked.

One example of a response to the cognitive aid prompt is a deferralrequest. The stored instance of the password can be used as the enteredpassword in response to the deferral request. The prompting period maybe reset based on the deferral request.

FIG. 7 depicts a process flow 400 for adjusting a prompting periodthreshold according to an embodiment. At block 402, a prompting policytable can be populated with a prompting period threshold associated witha user identifier and a website identifier. At block 404, the promptingperiod threshold can be dynamically adjusted according to the promptingpolicy 116 of FIG. 4 based on one or more of: an elapsed time since alast successful login, a level of password complexity, and a device typeused to access the website. At block 406, the prompting period thresholdcan be reset based on a user request or a resetting of a passwordassociated with the user identifier and the website identifier.

Technical effects and benefits include a cognitive password entry systemthat assists in password recall and reduces security risks that mayarise in frequent password resets due to users forgetting previouslystored passwords.
